in reply to 'use' falls out of scope at runtime

Are you saying that the second time you run that use, it doesn't reload an already loaded module? That's just how Perl works, but you can use workarounds like Apache2::Reload.

    no, it falls out... the module is not available.

    the only way to keep it in enviroment is to trigger the function calling 'use' for each run

      use called a second time doesn't reload the module, since it checks %INC (see perlvar) and, if the module is already in that hash, the underlying require just returns 1, so no loading. You would have to undef $INC{$module} for the use to reload the module. Keep in mind that in %INC the key for Some::Module is Some/

      Aa Corion said, you could use Apache::Reload for those packages; if you have changing packages where methods/functions are organized into files, you could use AutoReloader.
